To 11/] 101mm it may concern:

Be it known that I, VILLIAM II. VVAG- GONI'IR, a citizen of the UnitedStates, residing at Jeanerette, in the parish of Iberia and State ofLouisiana, have invented a new and useful Apparatus for Bleaching Cane-Juice, of which the following is a specification.

This invention relates to apparatus especially designed for use inbleaching juices such as the juices of sugar cane,beets, maple, etc, oneof its objects being to provide an apparatus which confines the sulfurfumes used for cleaning purposes so that they will not escape into thesurrounding atmosphere at any time during the bleaching process or atany point within the bleaching apparatus.

A further object is to provide means whereby a thorough commingling ofthe fumes and juice is effected so that a high efficiency is maintained.

Another object is to provide means whereby the juice, after leaving theapparatus, can be immediately returned thereto should it require furtherbleaching.

lVith the foregoing and other objects in view which will appear asthedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings: Figure 1 is a perspective view of the apparatus. Fig.2 is a central vertical longitudinal section therethrough. Fig. 3 is aplan view of the appa ra-tus, the top of the housing being broken awayand the various feed and outlet pipes being in section. Fig. l is anenlarged vertical transverse section on line AB Fig. 3.

Referring to the figures by characters of reference 1 designates a tankpreferably rectangular and which is divided by a transverse partition 2into separate compartments 3 and 4 respectively, the compartment 3constituting a receiver while the compartment -l constitutes thebleaching chamber. Compartment 3 is open at the top, whereas compartment4 is closed in any suitable manner, as by a removable top plate 5 whichcan be secured in closed position. in any preferred manner. An outletpipe 6 extends from the top of the bleaching chamber 4 to the limingapparatus not shown, and this outlet pipe may be provided with a faucet7 or the like designed to discharge into the supply chamber 3. Saidfaucet, however, is normally closed.

Extending through the bottom portion of the partition 2 and close to thebottoms of the chambers 3 and L is a tube 8 having one end open andclose to one end wall of the compartment 4, while its other end isclosed and in communication with a pipe 9 designed to direct sulfurfumes into the tube 8 from a suitable generator. Arranged within thetube 8 is a nozzle 10 adapted to discharge toward the open end of thetube 8 and this nozzle is in constant communication with the pipe 9.Discharging into the nozzle is a small pipe 11 in communication with asupply pipe 12 whereby steam or other suitable fluid under pressure isdischarged into the nozzle.

In using the apparatus, the sap or juice to be bleached is placed withinthe compartment 3 and flows through one or more ports 13 into the fine 8atpoints adjacent nozzle 10. The steam or other fluid under pressuredischarged into the nozzle from the pipe 11 creates a suction throughsaid pipe and downwardly through the pipe 9 so as thus to draw into thetube 8 the sulfur fumes which are discharged into pipe 9 from thegeneratornot shown. The force of the steam or other-fluid dischargedinto the nozzle serves to blow the juice longitudinally within the tube8, sucking it through the port or ports 13 and discharging it from theopen end of the tube 8 into the chamber 4. During this agitation of thejuice the sulfur fumes which are at the same time discharged into thetube 8, become thoroughly commingled with the juice and operate tobleach it so that, as the juice is discharged into the pipe 6 it will.if the apparatus is properly operating, be properly bleached. A sampleof the juice can be withdrawn through the faucet 7 and back into thechamber 3 whenever it is desired to ascertain whether or not the juicehas been properly bleached. If the bleaching has not been sufficient,the juice can be caused to flow through the faucet into chamber 3 andthen rebleached.

It will be seen that by means of apparatus such described, a thoroughwanna gling of the juice and the sulfur fumes can be effected withoutreleasing any of the fumes into the surrounding atmosphere.

While the apparatus is especially designed for bleaching uses, asheretofore pointed out, it will also be found useful as a means formixing two or more liquids by feeding them to the compartment 3 afterwhich any kind of fluid in the form of gas, vapor or liquid, can beinjected into the liquid as heretofore described, thus operating to drawthe liquid into the tube 8 and 'to force them into the compartment 4.

What is claimed is 1-- 1. Apparatus for bleaching cane juice, comprisinga receptacle subdivided into an open receiving compartment and a closedcompartment, a tube for establishing communication between the twocompartn'ients, means for directing a bleaching medium or the like intosaid tube, a nozzle within the tube, and means for directing a fluidunder pressure into the nozzle thereby to suck the said medium into thenozzle and discharge it into the contents of the tube and eject thecontents of the tube into the closed compartment, an outlet pipeextending from the closed compartment, and .ialved means for directingfluid from the outlet pipe back into the open compartn'ient.

2. Apparatus for bleaching cane juice including a casing sub-dividedinto a closed compartment and an open receiving compartment, a tubeconstituting means for maintaining cominunicatimi between the twocompartments, an outlet pipe extending from the closed compartment,means for directing fluid from the outlet pipe and back into thereceiving COlIlptll'tlllQIlt, and means for directing gas or the likeforcibly into the contents of the tube thereby to create a forcedmovementof the juice from the receiving chamber and into the closedchamher.

In testimony that I claim the foregoing as my own, I have hereto allixedmy signature in the presence of two witnesses.
